Definitions

  • the invention relates to the field of foam-producing devices by foaming-liquid-based pumps as defined in the preamble of claim 1.
  • the features of the preamble of claim 1 are known to those skilled in the art.
  • US 3,010,613 It relates more particularly to a device that adapts to non-specific pumps for the production of foam and allows them to produce foam from a foaming liquid.
  • Foam is used for many applications, for example as a styling foam, as a detergent or as a body care.
  • the foam has several advantages over a gel of the same nature.
  • An example is that the foam has a higher penetrating power to the gel and rinses more easily.
  • the foam is a ready-to-use product unlike a gel that needs to be mixed with water, for example, in a container or on the skin.
  • Another advantage is that there is no loss when applying the foam that is compact, unlike a gel that is less obvious to apply, for example, on the skin. The use of foam is therefore more economical.
  • the object of the present invention is to propose a device that adapts to pumps for liquid product, enabling them to produce foam.
  • a diameter matching member is connected between the pump inlet and the first end of the supply conduit.
  • the supply duct is made by an elbow tube having a right plunging portion and then a bend and a right emergent portion, the elbow being below the level of the foaming liquid and the suction hole being made in the elbow.
  • the supply duct is made of three tubular fitted parts, being an elbow, a dip tube and an emergent tube, the U-bend having two connection ends and a suction hole, the dip tube being connected to the pumping input and at a first end of the elbow, the emerging tube being connected to the second end of the elbow and emerging in the air.
  • a rigid member connects the reservoir to a portion of the emerging tube in the air within the reservoir.
  • a rigid member connects a portion of the dip tube to a portion of the emerging tube in the air within the reservoir.
  • the emerging tube opens into the air outside the tank via a valve through the wall of the tank.
  • the ratio between the diameter of the hole and the mean diameter of the supply duct has a determined value.
  • At least one additional refining gate is placed in the expulsion conduit, so as to obstruct the expulsion conduit.
  • an expansion grid is placed at the outlet of the expulsion duct, so as to obstruct the expulsion duct.
  • the part of the enlargement grid obstructing the duct is composed of three horizontal blades.
  • the part of the enlargement grid, obstructing the conduit is composed of two blades forming a cross.
  • the pump includes an inlet (301) and a pumping outlet (302).
  • the pumping device comprises a chamber (3) for pumping.
  • the pumping chamber (3) is cylindrical in shape and narrows at its lower end by a cone.
  • the pump inlet (301) is at the end of the cone.
  • the inlet (301) comprises a ball valve (3001) which controls the opening towards the lower part of the chamber (3) for pumping.
  • the chamber (3) is closed at its upper end by a double piston (3004, 3003, 3005, 3006, 3009).
  • the double piston (3004, 3003, 3005, 3006, 3009) is so named because it comprises a central portion (3003) in sliding pivot connection, over a predetermined length with a peripheral portion (3004).
  • the outer edges of the peripheral portion (3004) of the double piston (3004, 3003, 3005, 3006, 3009) have a "V" profile and are pressed against the wall of the chamber (3), thereby providing double guiding piston (3004, 3003, 3005, 3006, 3009) and forming a tight connection.
  • the central portion (3003) has an upper flange (3005) and a lower flange (3006) being translational stops in translation of the peripheral portion (3004).
  • the connection between the central portion (3003) and the peripheral portion (3004) is sealed. Sealing is enhanced when the peripheral portion (3004) abuts a flange (3005, 3006), the peripheral portion then being compressed and deformed.
  • the central portion (3003) is tubular and hollow and includes one or more ports (302) that form the pump outlet.
  • the interior of the central part (3003) communicates with the interior of the chamber (3) pumping by this or these orifices (302), when the portion (3004) peripheral does not abut on the flange (3006) low.
  • a return spring (3007) is placed in the pumping chamber (3) and bears against abutments (3008) of the pumping chamber (3) at its lower part. The upper part of the spring bears on a pin (3009) formed on the portion (3003) of the central double piston (3004, 3003, 3005, 3006, 3009).
  • FIG. figure 1 A non-limiting example of the structure of the adaptation device is shown in FIG. figure 1 .
  • the means (3000) of pumping an example of which has been previously described, is symbolized by a frame (3000). Only the pump outlet (302) and the pump inlet (301) are shown.
  • a supply duct (1) is connected to the pump on the pump inlet (301).
  • This duct (1) has a plunging portion (104), a bent portion (102) and an emergent portion (101).
  • the plunging portion (104) drops below the level (11) of the foaming liquid (10). It is extended by an elbow (102) in which a suction hole (103) is made.
  • the suction hole (103) forms the inlet of the foaming liquid.
  • the suction hole is made at a position corresponding to the bottom of the tank (8a, 8b) so that the foaming liquid (10) can, as long as possible, be sucked by this hole (103).
  • the hole (103) is formed on the side of the bend (102) so as not to be in contact with any impurities or agglomerations in the bottom of the tank (8a, 8b).
  • the elbow (102) is extended by an emergent portion (101) that rises above the level (11) of foaming liquid (10) and emerges into the air (12) within the reservoir (8a, 8b).
  • a rigid holding piece (105) is attached to the pumping device (3000) and to the upper part of an emergent portion (101) of the supply conduit (1). This device (105) for holding is intended to keep the end of the duct (1) of supply in the air, in the case where the duct (1) is made of a flexible material.
  • the emergent tube emerges in the air outside the tank (8a, 8b), via a valve (1020) passing through the wall of the upper part of the tank (8a).
  • a valve (1020) passing through the wall of the upper part of the tank (8a).
  • the tube (102) is held by a fitting in or on the valve (1020).
  • the valve (1020) creates an air inlet in the pipe (102), while preventing a flow of fluid exiting the pipe (102).
  • the embodiment is more complicated because it requires making a hole in the upper part of the tank (8a).
  • the valve is placed in the hole in a sealed manner, which represents an additional constraint.
  • the flapper increases the cost of the device.
  • This embodiment is given by way of non-limiting example and has an operation equivalent to that of a pipe emerging in the air (12) inside the tank (8a, 8b).
  • a pipe emerging in the air (12) inside the tank (8a, 8b) is given by way of non-limiting example and has an operation equivalent to that of a pipe emerging in the air (12) inside the tank (8a, 8b).
  • the supply duct (1) is composed of three parts: a U-shaped bend (103), a first plunger tube (104) and a second (101) emerging tube.
  • the elbow is connected to the two tubes (101, 104) and has a suction hole (103) formed, in a non-limiting manner at a 45 degree angle.
  • the plunger tube (104) is further connected to the pump inlet (301).
  • the emerging tube (101) opens into the air (12).
  • the suction hole is not present and is replaced by a small amount of diffusion device.
  • this diffusion device comprises a valve located above a hole of determined size and shape.
  • the duct is made in three parts, the diffusion device being in the tubular elbow (103).
  • a non-specific foam pump can be easily modified according to the invention to become a foam pump.
  • the liquid (10) is sucked into the pumping chamber (3) through the pump inlet (301) which is connected to a dip tube whose end comes below the level (11) of the foaming liquid (10).
  • this dip tube is disengaged from the pumping inlet (301) and replaced, for example, by an elbow feed pipe (1) according to the invention.
  • the disengagement and the interlocking of the conduit (1) supply according to the invention are manually, without difficulty, in the portable pumps.
  • the dip tube, present in the original pump, is no longer present because it has been replaced by the conduit (1) supply according to the invention.
  • the conduit (1) supply according to the invention, is set up, by means, directly on the inlet (301) pumping.
  • the structure of the adaptation device also includes, without limitation, one or more grids (2, 201, 6), as shown in FIGS. figures 1 and 4 .
  • the pumping outlet (302) opens into an expulsion conduit (4) which terminates in a projection head (5).
  • the filtering grid (2) is placed in the expulsion duct (4).
  • the mesh size of the grid (2) will be detailed later.
  • a round grid, of the same diameter as a conduit (4) for circular expulsion is positioned across the conduit (4) expulsion perpendicular to the direction of flow.
  • the expulsion duct (4) is thus obstructed, that is to say that the filtering grid (2) occupies the entire duct without sealing it hermetically.
  • an oval grating is placed obliquely in a circular expulsion conduit (4).
  • the dimensions of this oval grid correspond to those of the circular duct, so that the grid bears on the entire inner periphery of the duct (4) expulsion.
  • the oval grille obstructs the duct (4) expulsion.
  • an expulsion conduit (4) having an indeterminate and rounded shape is associated with a flexible grid which conforms to the shape of the expulsion conduit (4), obstructing the conduit (4).
  • one or more additional grids (201) for filtering are added in the expulsion conduit (4), across the expulsion conduit (4).
  • additional grids (201) are placed after the first filtering grid (2), according to the direction of flow of the fluid in the expulsion conduit (4).
  • several additional grids (201) for filtering are added in the expulsion conduit (4).
  • a space remains between each grid.
  • a spacer (202) is placed between two grids (201, 2).
  • two grids are placed one above the other, joined, and are equivalent to a finer grid.
  • an enlargement grid (6) is added to the projection head (5). This last grid (6) is intended, but not limited to regulating the flow, widen the jet or change the structure of the jet.
  • the various grids (2, 201, 6) are held in the pump, in a nonlimiting manner by clamping or gluing.
  • the filtering grid (2) has one or more degrees of freedom with respect to the pipe (4) for expulsion of the pump and obstructs the conduit (4) for expulsion, whatever its position.
  • the pumping device expels the fluid through a pump outlet (302) connected to an expulsion conduit.
  • the expulsion duct is disassembled and a filtering grid (2) is fitted into the duct so as to obstruct it.
  • Another embodiment is to fix the grid in the duct by gluing.
  • the projection head (5) is located approximately 4 cm from the pumping outlet (302) and the duct is composed of three pieces, as shown in FIG. figure 4 . It is therefore possible to insert several filtering grids with a space between each grid. In a nonlimiting manner, the grids are held tight in the duct or fixed by gluing. In another embodiment, two grids are held apart from each other by a spacer (202). In an industrial process, the filter grids (2, 201) are inserted into the expulsion duct (4) before or during the assembly of the pump.
  • the pumps comprise a pump drawing liquid through a dip tube and expelling the liquid through a conduit (4) for expulsion ending in a head (5) projection.
  • the user actuates the pump manually by pressing on the head (7) of the pump.
  • the liquid, such as soap, is pumped in half time.
  • the first phase represented at figure 2
  • the first phase takes place when pressing on the head (7) of the pump.
  • the second phase represented at figure 3 , is the filling of the chamber (3) pumping. This phase takes place when the piston returns to the initial position.
  • a spring compressed during the first phase exerts a force in the second phase, allowing the reassembly of the double piston (3004, 3003, 3005, 3006, 3009).
  • a double arrow symbolizes the movement of the double piston (3004, 3003, 3005, 3006, 3009) relative to the chamber (3) and a single arrow symbolizes the displacement of the fluid.
  • the chamber (3) has two openings for fluid circulation: a pump inlet (301) and a pump outlet (302).
  • the openings (301, 302) are associated with an opening and closing system allowing the fluid to pass only in one direction.
  • valves control the opening of the inlet (301) and the outlet (302) pumping.
  • a system (3001) using a ball prevents, in the first phase, the fluid from leaving the chamber (3) pumping but let the liquid enter in the second phase.
  • the ball is held between lateral stops (3008), an upper stop and the opening of the chamber (3).
  • the upper stop is made in this example by a bearing surface of the spring.
  • the double piston (3004, 3003, 3005, 3006, 3009) has a similar role for the pump outlet (302). It opens the pumping outlet (302) during the expulsion phase, shown in FIG. figure 2 , and it blocks the pumping outlet (302) during the suction phase, shown in FIG. figure 3 .
  • the opening or closing of the pumping outlet is related to the movements of the piston.
  • the movable portion (3004) is then resting on the flange (3005) of the upper double piston (3004, 3003, 3005, 3006, 3009) and therefore exerts pressure on the liquid contained in the chamber.
  • the liquid is then expelled through the central passage (302).
  • the double piston rises under the action of the spring (3007), but its movable portion (3004) is retained by the friction forces exerted by the chamber (3) on the movable part.
  • This moving part (3004) then descends, with respect to the double piston (3004, 3003, 3005, 3006, 3009) and comes to bear on the flange (3006) low, thus blocking the opening (302) central.
  • the rise of the double piston (3004, 3003, 3005, 3006, 3009) then creates a suction in the chamber (3).
  • a pumping device as shown in Figures 2 and 3 is associated with a structure according to the invention, represented in FIG. figure 1 , in a non-limiting way.
  • the foaming liquid is first drawn through the suction hole (103) together with the air (12) from the portion of the pipe above the level (11) of the liquid (10).
  • the emulsion begins as soon as the foaming liquid (10) is sucked by this hole (103).
  • the conduit (1) supply therefore contains only air before the bend in which is formed the hole (103) suction.
  • the supply duct (1) contains a mixture of air and foaming liquid. This mixture is then stirred in the pumping chamber (3).
  • a coarse emulsion is then in the chamber.
  • the fluid is then filtered and emulsified more firmly by a filtering grid (2) at the outlet of the pumping chamber (3), in order to obtain foam after the grid (2).
  • the foam is then expelled by the projection head and the enlargement grid.
  • the foam production process is also based on one or more grids (201, 6). These are on the one hand additional grids (201) filtering for tamping the foam and secondly gates (6) for regulation or enlargement. These optional grids are added if the structure of the pump allows it.
  • the grid or grids (201) added to compact the foam make it possible to have a more dense foam.
  • These grids (201) for additional filtering are placed, according to a nonlimiting example, one after the other, in the conduit (4) of expulsion with a space between each of the grids. Each of these grids cup the foam, which becomes more and more dense.
  • the mesh of the grids (201) additional is increasingly thin.
  • a removable grid (6) widening or regulating the flow adapts, without limitation, on the head (5) projection. It makes it possible to modify the structure of the foam or, respectively, to regulate the flow of foam.
  • nonlimiting examples are: a plastic ring having equidistant parallel blades or a ring having two cross blades, in order to separate the foam jet.
  • the adaptation device according to the invention is composed of several elements that fit on non-specific pumps for the production of foam.
  • the elements added to a pump have dimensions within a functional range.
  • the variation of the dimensions makes it possible to obtain different structures of the foam or different flow rates.
  • the dimensions also depend on the foaming liquid, depending on whether it is more or less foaming or more or less diluted.
  • the diameter of the suction hole of the foaming liquid in the feed duct (1) depends on the viscosity of the foaming liquid (1). The more viscous the liquid, the larger the diameter of the hole. For the same liquid, different diameters of the hole are possible.
  • the maximum size is the size limit for which, when the pump is at rest, it there is no rise of the foaming liquid in the conduit (1) supply. Beyond this maximum size, when the pump is at rest, the liquid rises in the supply duct (1), arriving in a nonlimiting manner up to the level (11) of the liquid (10) foaming in the reservoir ( 8a, 8b).
  • the minimum size is the size below which the foaming liquid is not sucked during pumping.
  • the size of the diameter of the suction hole (103) partly determines the nature of the foam. The larger the diameter, the greater the proportion of foaming product in the foam will be important.
  • the diameter of the supply duct (1) also has an influence in the production of the foam. The smaller the average diameter, the more sucked air will be braked. The air flow sucked by pumping the pump, will be slower.
  • the velocity of the air (12) at the suction hole (103) influences the amount of liquid sucked. Without limitation and remaining within operating ranges, the greater the average diameter of the duct (1) supply, the greater the proportion of air (12) contained in the foam, and the more the foam will be light . Conversely, the feed conduit (1) has a maximum average diameter.
  • the air does not pass quickly enough to the hole (103) to create a phenomenon of suction of the liquid (10) foaming through the hole (103) suction.
  • the ratio between the size of the hole (103) and the diameter of the pipe must be judiciously adapted.
  • the inner diameter of the feed duct may vary from 3 mm to 15 mm and the diameter of the suction hole may vary from 1 mm to 5 mm. These examples of diameters are functional but depend on the product used.
  • the filter grid also has a role in the nature of the foam. Its dimensions affect the fineness of the foam and therefore its density. The more the grid (2) of filtering will have a fine mesh, the more the foam will be dense. On the other hand, in a nonlimiting manner, the mesh size of the grid is a function of the dimensions of the other elements and also of the dilution of the foaming liquid (10). In another exemplary embodiment, additional filtering grids (201) are added in the expulsion conduit (4). Of In a nonlimiting manner, the mesh sizes of the filtering grids (2, 201) are chosen from the first filtering grid (2) to the last additional filtering grid (201), the last additional grid being the closest to the head (5) projection.
  • a grid (6) movable widening is placed at the head (5) projection.
  • This grid (6) mobile allows the device to operate in two modes, with or without the grid (6).
  • the enlargement grid (6) allows either to widen the foam jet or to regulate the foam jet.
  • the foaming liquid becomes foam when it is mixed with water and is stirred.
  • the device according to the invention allows the production of foam without additional water supply.
  • the foaming liquid (10) contained in the reservoir (8a, 8b) therefore contains a product having foaming properties diluted with water.
  • the dilution of the foaming liquid is carried out according to a mixture comprising 20% to 80% water.
  • An example of an active agent is, for example, a styling element in a styling mousse.
  • the foaming liquid (10) is composed of an active agent, applied to the hair, a foaming agent and water.
  • the dilution is carried out according to the dimensions of the other elements of the device according to the invention.
